Bridge
The bridge connects Hyperliquid to Arbitrum for USDC deposits and withdrawals. It is secured by the validator set and has been audited by Zellic.
Deposits
- Validators sign deposit transactions
- Deposits are credited when >2/3 of staking power has signed
- No user-side Arbitrum ETH required
Withdrawals
- Balance immediately deducted from L1
- Validators sign the withdrawal as separate transactions
- When >2/3 staking power has signed → EVM transaction requests withdrawal
- Dispute period follows — bridge can be locked if withdrawal doesn’t match Hyperliquid state
- Cold wallet signatures of >2/3 stake-weighted validators required to unlock
- After dispute period → finalization transactions distribute USDC
Withdrawal fee: 1 USDC (covers Arbitrum gas costs of validators)
Security
- Dispute period protects against malicious withdrawals
- Cold wallet multisig prevents unauthorized unlocking
- Full bridge code available on Hyperliquid GitHub
- Audited by Zellic (see Audits section)
Risk
The bridge is the primary smart contract risk surface for Hyperliquid. Bugs or vulnerabilities in the bridge contracts could result in loss of user funds.
